1. **Problem Statement:** Determine whether the relation in graph (b) is discrete, continuous, discontinuous, or neither. Then state its domain and range. 2. **Graph Description:** Graph (b) is a straight line passing through the origin with slope 1, extending diagonally from bottom-left to top-right. 3. **Understanding the Relation Type:** - A line is a continuous relation because it has no breaks or gaps. - It is not discrete (which consists of isolated points). - It is not discontinuous (which would have breaks or jumps). 4. **Domain and Range:** - The domain is all x-values covered by the graph, approximately from $-3$ to $4$. - The range is all y-values covered by the graph, approximately from $-3$ to $3$. 5. **Summary:** - Relation type: continuous - Domain: $[-3,4]$ - Range: $[-3,3]$
